[jboss-dev-forums] [Design of JBoss jBPM] - changing access on variables to separate attributes

[kukeltje]

Currently the attribute access on variables is defined as a combination of the values 'read', 'write' and 'required'.

I'd propose to change this to 3 separate attributes. Let me explain why:
- This is more in line with web/form frameworks (e.g. jsf, xforms)

Comments/thoughts?
